Just this morning at Barclays, one former Lehman employee freaked out when his computer wouldn't turn on. It turned out it was just a loose power cord somewhere. But the employee didn't realize this until he had let loose a tirade of obscenities directed at his new Barclays bosses and Lehman CEO Dick Fuld, according to a witness. Now co-workers are wondering if his premature panic may cost him his job.
